Ample evidence has been presented and uncovered by the Mueller investigation, the DOJ, the US Senate Intel committee and the US House investigations regarding Flynn, Manafort, Stone, Gates, Cohen, Parnas, Fruman and other corrupt, criminal individuals associated with Trump and his campaign. Several people have been indicted, tried and convicted as a result of those investigations
All of this counterattack “Obamagate” bullshit has been orchestrated by Barr has and is just an attempt by Trump’s bagman AG to in the words of House Intel Committee chair Adam Schiff “flood the zone with excrament” and create a smokescreen in order to deflect away from the facts.
The facts are that Trump surrounded himself with a bunch of crooked scumbags, some who were being groomed by foreign agents and criminals, (some of them were being paid large sums of money) before, during and after they became a part of Trumps campaign and or his administration.
Notice that several of Trump’s associates have been indicted, tried and convicted already. Cohen, Manafort and Stone, Flynn, Gates Cohen and others have plead goulty and turned into informants for the prosecution.
Notice how Barr has not indicted anyone but just uses innuendo and smear tactics to trash his own department at the behest of his benefactor, Trump. Arresting, indicting and convicting you’re target is very hard to achieve unless he is guilty as hell. Flooding the zone with bullshit and trashing someone without giving him or her their day in court is easy. That’s Barr/Trump’s game.
